A method and apparatus for testing of the frost - tau - resistor and / or of the frost - de-icing - resistance of a solid body

摘要

a review solid-state (1) is first defined in an ultrasonic bath is cleaned. it shall then be stored in a temperature controlled room and dried. thereafter the solids with the weather exposed beanspruchungsflu00e4che (1a) to the bottom in a sample chamber (2). the sample chamber contains water (12) or an aqueous solution containing tausalzen.the level of the pru00fcfmediums in the sample chamber is chosen such that the solids from below is wetted. the solid is stored as long as in the sample chamber, and by absorbing the kapillares pru00fcfmediums has reached a defined degree of saturation. subsequently, the sample chamber in a temperierbad (8) is used.with the help of the temperierbades is solid a frost - dew - change rapidly. thereafter the solids in the sample chamber in an ultrasonic bath. loose or abgewitterte parts of the beanspruchungsflu00e4che dissolve in ultrasonic bath of the solid.they are separated, dried and weighed, and form a defined level for the abwitterung at due to the frost - dew - change.
